Worm Tower of Power – Vermiculture Vermicomposting System
httpv://www.youtube.com/watch?v=QKk6AWwm7IA Wow, I've never seen a stacking system done quite like this before! I'm tempted to try something like this, since it has such a small footprint and can handle a pretty serious volume of material. Something like this looks like it would cost under $20, not bad for an item that handles a heck of lot more than the Worm Factory for a fraction of the price...
